Honestly, I can get why they didn’t want to do that, though IMO they could have at least made Shego’s skin paler since honestly it was always more of a chalk-white to me rather than green. There’s already plenty of cosplay tutorials on YouTube showing how to pull Shego off, after all! But for what they did, the costumes themselves are incredibly on point for those two.

As for Shego’s powers being gauntlets this time – that was actually the original explanation. It got changed at some point and some of the secondary sources failed to update it until later.
